IMPROVEMENT IN WINDMILLS.

To all whom it may concern:

in Windmills; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in whichy Figure 1, Plate 1 ,is a perspective view of my improved windmill, with the vane, the windwheel, and part of the supporting-post broken oft'. Fig. 2, Plate l, is a top view of the same. Fig. 3, Plate 2, is a section taken vertically through the center ofthe same. Fig. 4, Plate 2, is a sectional view in detail of the verticallyadjustable tube and guide-plate at the bottom of the mill-post.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to certain novel iinprovements on windmills of that class wherein the wheel-shaft is arranged on one side of the vertical center of the mill, so that it will edge more or less to the wind, according to the force thereof, as will be hereinafter explained.

The following description of my invention will enable others skilled in the art to understand it. y

In the accompanying drawing, A represents the mill post or standard for supporting the Wind-wheel, thelvane, and the parts connected thereto for actuating the same. B represents a cylindrical cap, from which extend out horizontally three arms, b b and D. The arms b b have tubular bearings formed on them for supporting the shaft G of the wind-wheel. The wind-wheel, which is not represented in the drawin g, may be constructed in any well-known manner, its blades being rigidly secured to their hub and the latter secured to the outer end of the shaft C. 0n the inner end of the wheelshaft C is a crank, c, which turns in a slideblock, c, working in an oblong slot, cl, formed in one end of a vibrating rod, D. This rod D is pivoted to the outer end of the arm D', and it has pivoted to it the mill-rod N that extends down centrally through the post A, and has a swivel-piece, S, attached to its lower end. It

is by means of this swivel-piece S that the rod N is attached to the piston-rod of a pump, or to any other machine which it is desired to operate. The rod D works between guides e :and receives from the crank C a vertical motion. The cap B receives within it a cup-shaped hub, fu, which is a cylindrical enlargement formed on the upper end of a tube, m. This tube is received into the post A and turns freely in a metallic cap, a., which is secured to the upper end of the post, and on which is supported the said cup-shaped enlargement c, as shown in Fig. 3.V Inside ofthe cup c is an inclined elevation, 19, on which is supported the capB by means of a small anti-friction roller, o, which is applied to aflange fixed to the inside of the cap B. If desirable, the roller o may be applied on the cup e and the inclined plane on the cap B. The cap B and wheel-shaft C are, by the above means, allowed to turn freely in a horizontal plane, either with the cup-shaped 'enlargement u or independently of this enlargement. The cap is kept in its place by means of a long tube, a, which is formed on it, and which extends down tothe bottom of the post A and receives into its lower end a verticallyadjustable tube, t, as shown in Fig. 3. An arm, G', extends out radially from the base of the cup c, and has rigidly secured to it the vanestock G. On one side of this vane-stock G is secured a slotted plate, f in the slot of which plays one end of a rod, f, the opposite end of which is pivoted to an arm, e', extending out at right angles from the arm D. To that end of the rod f which is applied to the slotted plate f a link, g, is attached, to which a rope, g1, is fastened, which rope passes over a pulley on an arm, g2, and is again fastened to the upper end of a rod, h, shown in Fig. 3. This rod extends down through the tube a and into the vertically-adjustable tube t, and is secured to a swiveling portion, s. longitudinally, and into its grooves short tongues extend, which tongues are formed on a plate, i, secured to the bottom of the'post A. This will allow the tube tto be moved up and down, but will prevent this tube from rotating. The portion s in the lower end of the tube t, through which the prismatic rod N passes'and to which the rod h is secured, is allowed to rotate freely with the rod N, which will prevent the rod h from winding around the rod N., The weight of the wind-wheel, the weight of the cap B, and the weight to be lifted, which is connected to the swivel S, is sustained upon The tube tis grolovedl 2 remesa the inclined plane p. Consequently any dcviation ofthe Wheel-shaft C from its normal position- Which position is in aline parallel to the line ofthe vane-stock G-Will cause the wheel, the cap B, and the rod N to be lifted. Thus it will be seen that as the Wind-Wheel deviates from its normal position (face to the Wind) itwill be lifted on the inclined plane 2f, carrying up with it any Weight Which is attached to the lower end of the rod S.

The greater the Weight to be lifted, the greater will be the force required to move the Wheel from its normal position-that is to say, the Wheel Will edge to the Wind more or less, according as the resistance on the rod N is increased or diminished.

The vertically-movable tube t has a rod, R, attached to it, by means of which a person can, by pulling on it, move the wind-wheel to any position he may desire, and, When necessary, he can move the Wheel full edge to the windthat is to say, out of Working position-as indicated in dotted lines, Fig. 2.

Having described myinvention, what l claim new, and desire to secure by Letters Patent,

l. The cranked wind-Wheel shaftG, arranged eccentric to the vertical axis ofthe post A, and having its bearings on arms b b of a cap, B, which latter is caused to rise and descend as the wind-wheel edges more or less to the wind,

substantially as described.

2. The vibrating arm D, having the rod N connected to it and supported by the verticallymovable cap B, substantially as described.

3. The vane-arm G, radiating from an enlargement,o,on a tube, m, in combination with the vertically-movable cap B supporting the wind-Wheel shaft, substantially as described.

4. The rod f, connected to the vanestock G and to the arm D of cap B, as described, in combination with the drawing-down connections gl l1., substantially as set forth.

The vertically-sliding (but not rotating) tube tand swivel s, receiving through them the rod N and applied to the tuben and tongued plate i, substantially as described.
